Ref. [1]} introduces a no-go theorem that assuming quantum mechanics is applicable to the scale of an observer, then one of the three assumptions, `Locality', `No-superdeterminism', or `Absoluteness of Observed Events (AOE)' must be false. Here AOE means that “every observed event exists absolutely, not relative to anything or anyone" [1]}. The no-go theorem is supposed to be independent of underline physical theory and is proved in the context of extended Wigner's friend (EWF) scenario [3]}, as shown in Figure REF . The measurement results from the friend in the lab can be correlated with the super-observer's subsequent measurement results. Suppose the measurement outcomes from Alice, Bob, Charlie, and Debbie are \(a, b, c, d\)  respectively. Alice can have three different measurement settings, labeled by parameter \(x \in \lbrace 1,2,3\rbrace \) . When \(x=1\) , Alice opens the \(L_1\)  and asks Charlie's measurement outcome, while when \(x=2,3\) , Alice performs a different measurement on \(L_1\) . Similar measurement settings for Bob are labeled as \(y\in \lbrace 1,2,3\rbrace \) .
